Each Amazon account has a name and e-mail address associated with it, as well as a 12-digit account identifier (ID). When you have an Amazon Machine Image (AMI) shared with you, or when you share an AMI with another Amazon account, you may need to provide this number. Below is one way you can find your account number.
- Log in to the AWS Management Console.
- At the top of the page, click the link that is your account name.
- Click My Account.
- Your 12-digit account ID is listed under Account Settings.
